Depression after heart procedure

[JLH1960]

I am a 55 year old woman who in January unexpectedly had 2 stents inserted in my LAD to open a 99% blockage and a 70% blockage.  I now take toporal, lipitor, plavix and estradial.  I am 5'8", 215 lbs.  I am involved with cardiac rehab 3x a week.  My resting BP typically is 110/70.  I feel more tired now then before the procedure.  I wake up tired.  I struggle with depression.  There is a commercial on TV that states 50% of people with coronary heart disease die within 5 years - is that statistic accurate?  I am trying to reduce sugars from my diet but struggle with that as I am an emotional eater.  I've read your earlier responses suggesting reducing stress but my job involves stress and I can't just quit my job.  I am anxious and fearful any time a new pain occurs within my body thinking it could be a blood clot.  Is depression/anxiety after surgery common?  Will the fatigue ever subside?
